Autumn is coming, what are the changes in plants and animals?

Autumn is coming, and there are noticeable changes in both plants and animals.

Changes in plants mainly include defoliation and wilting, as well as deepening of leaf color. The leaves of many deciduous perennials will gradually change color, wither, and fall, leaving only the branches to survive the winter. Annual herbaceous plants will come to the end of their lives, withering and dying.

These changes cause the plants to gradually go into dormancy in response to the coming cold season.

The changes in the animals are mainly manifested in migration and thickening of body hair. Many animals choose to migrate to more suitable environments in the fall, or store enough energy to survive the winter. Some animals, such as squirrels and bears, cope with cold weather by thickening their body hair to maintain their body temperature.

Whether it's plants or animals, they are struggling to adapt to the upcoming seasonal changes to ensure survival.

When autumn comes, plants lose their leaves (or darken their leaves) and wither; Animals migrate or have thickened body hair; This is done to protect against the cold in winter.

The weather has changed from warm to hot, long sleeves have changed to short sleeves, animals have come out of hibernation and the plants have turned dark green

Summer is here, indicating that the rainy season is coming

Plants are the season of harvest, fruiting and flowering, and people are similar, working hard in autumn and reaping money in the New Year.

Autumn ants follow the road, accompanied by the warm sun, carrying charming food. In autumn, the lively and lovely little swallows fly south, the birds that are not afraid of the cold begin to store food and build nests, the small fish swim to the depths of the river, the frogs jump into the pond, the cicadas on the trees stop singing, the crickets on the ground stop calling, and the animals are ready for winter.

Autumn is coming, and the animals are busy. Ants start storing food in the summer, little squirrels pick up fallen pine cones on the ground, little bees fill honey that have been stored one by one, and little swallows fly south and come back after winter. There are also some hibernation animals such as turtles, snakes, hedgehogs, frogs that have also prepared food for the winter.

Autumn animals are magpies, grey magpies, sparrows, owls, woodpeckers, hares, voles, weasels, foxes, wolves, wild boars, bears, deer, roe deer, crickets, grasshoppers, etc. In early autumn, you can also see frogs and snakes. 2. Autumn represents plant characteristics:

The maple leaves turn red, the chrysanthemums bloom, and the osmanthus flowers are fragrant. 3. Autumn represents animal characteristics: geese fly south, squirrels store winter food.

Answer 1: Autumn animals include magpies, gray magpies, sparrows, owls, woodpeckers, wild mouses, voles, weasels, foxes, wolves, wild boars, bears, deer, roe deer, crickets, grasshoppers, etc. In early autumn, you can also see frogs and snakes. 2. Autumn represents plant characteristics:

The maple leaves turn red, the chrysanthemums bloom, and the osmanthus flowers are fragrant. 3. Autumn represents animal characteristics: geese fly south, squirrels store winter food.

We generally don't have any animals in autumn except for the small beans that grow in autumn, and we don't see anything else except ants.

The changes in the animals in autumn are: the animals will be busy storing food and digging manuscripts, and moulting due to the drop in temperature, most of which are caused by temperature changes. Lower animals die or hibernate, higher animals lie dormant or remain unaffected.

For example, fish activity decreases, but they do not hibernate. Amphibians hibernate. Some of the birds are migratory, some are not affected.

Some of the mammals migrate, some hibernate, and some remain unaffected.

In the autumn season, in nature, the yin and yang begin to change, the yang gradually retreats, the yin gradually grows, the climate changes from hot to cold, and the laughing things grow with the cold and gradually decline, which is the season of alternating between hot judgment and filial piety and cold. As the temperature gradually drops, the leaves of many deciduous perennials will gradually change color, wither, and fall, leaving only the branches to survive the winter. The annual herbaceous plants will come to the end of their lives, withering and dying.

Seasonal transitions encompass many climatic characteristics, and it is inaccurate to judge autumn based on temperature alone. The most noticeable change in autumn is when the leaves of the plants change from lush green to yellow, and begin to fall and the crops begin to ripen.

The changes in autumn plants are as follows:1. Ginkgo tree: Ginkgo biloba is a tree of the Ginkgo family and Ginkgo family, and the leaf color will change in autumn, and the leaves will gradually turn yellow, and then gradually fall off.

2. Rowan: The leaves of rowan are green in spring and summer, and turn bright red in autumn.

3. Creeper: The leaves of the creeper are green in spring and summer, and turn bright red in autumn.

4. Coptis chinensis: The leaves of Coptis chinensis will turn orange-red in autumn.

Autumn is generally characteristicIn China, the "beginning of autumn" of the 24 solar terms is traditionally used as the starting point of autumn. Entering autumn, it means that rainfall, humidity, etc. tend to drop or decrease. In nature, the yin and yang energy begins to change, the yang energy gradually retreats, the yin energy gradually grows, the climate changes from hot to cold, and everything grows with the cold and gradually declines.

According to modern meteorology, the autumn in the north temperate zone is on August 23 (summer heat) and November 22 (light snow); Autumn in the southern temperate zone falls on February 19 (Northern Hemisphere rain) and May 21 (Northern Hemisphere Lesser Man).

In the autumn, the main change of animals is to gradually enter a state of hibernation, most animals will prepare a food for the winter, or eat more food to ensure an energy of their body, including eating a lot of things when hibernation in winter.

Then, after the temperature drops, the animal will also moult, because the temperature change causes such a moulting phenomenon. Moreover, there are some animals that will fly from colder places to warmer places to carry out a process such as wintering, including a phenomenon such as the southward flight of geese, so in autumn animals probably have these changes.

For example, many migratory birds go south for the winter, such as geese, swans, red-crowned cranes and so on.

The more common resident birds in northern autumn include magpies, gray magpies, sparrows, owls, woodpeckers, turtle doves, pheasants, etc.; The more common mammals are hares, voles, weasels, foxes, and wolves, wild boars, bears, deer, roe deer and other animals can also be seen in some mountainous areas. Insects such as crickets and grasshoppers are active in early autumn, and frogs and snakes can also be seen in early autumn. (mainly for North China and Northeast China).

In autumn, the most noticeable changes in the natural landscape are the trees, when the city begins to sweep away a large number of fallen leaves, and the mountains are crowded with tourists who enjoy the autumn leaves. Autumn, the third season of the year, the transition season from summer to winter, the lunar calendar is from the beginning of autumn in July to the beginning of winter in September, the solar calendar is from September to November, and the astronomical calendar is from the autumn equinox to the winter solstice.

Meteorologists study phenology based on the following: after a hot day, the five-day average temperature is below 22 degrees Celsius, and autumn is considered to be autumn, and autumn ends when it is below 10 degrees.

There are a total of 6 solar terms in autumn, which are the beginning of autumn, the summer heat, the white dew, the autumn equinox, the cold dew, and the frost.

The leaves will gradually change color, wither, and fall, leaving only the branches to survive the winter.

Most plants lose their leaves in autumn. It is an adaptation of the plant to survive the cold season. In late autumn or early winter, due to the decrease in temperature, the absorption of roots is weakened, and the water supply of plants is difficult, which affects the photosynthesis and transpiration of plants.

Introduction

At this time, the leaves enter a state of senescence. On the one hand, the amount of auxin that inhibits leaf shedding decreases, and on the other hand, a large amount of abscisic acid is formed that causes the leaves to fall off. As a result, the leaves of the plant gradually fall off in autumn as the weather gets colder.

Defoliation is a good adaptation phenomenon for plants to keep their bodies hydrated and survive the winter safely.

Autumn fruits include domestic and imported mainly including: apples, bananas, oranges, hawthorns, sugarcane, pears, watermelons (autumn watermelons, small watermelons, etc.), lemons, grapes, American grapes, oranges, grapefruits, mangoes, jujubes (varieties, winter dates, winter dates, red dates, etc.), pomegranates, autumn peaches, persimmons, oranges, kiwi fruit, honey claws, tomatoes, dragon fruits, caryophyllus, lugan, nanguo pear, walnuts, lotus hearts, dried longan, dried lychees, water chestnuts, millet, brown fruit, longan, mango, olives.

In autumn, what changes in flora and fauna are mainly reflected in the natural landscape and animals. The most noticeable change in the natural landscape is the trees, with the city sweeping away a large number of fallen leaves, and the mountainous areas flocking to the autumn leaves. In autumn and autumn, the body of animals with hibernation habits begins to change, mammals.

Start stocking up on food for the winter.

Insects begin to change to overwintering insect states, deciduous plants begin to lose their leaves, and evergreen leaves begin to thicken and become smaller. Autumn, also known as autumn, is the third season of the year, the transition season from summer to winter, in the northern hemisphere.

For September-November, the Southern Hemisphere.

From March to May, the astronomical period is from the autumn equinox to the winter solstice.

Evergreens have not changed much, the leaves of deciduous trees have turned yellow and some red, and they have begun to lose their leaves, and chrysanthemums and hyacinths bloom in autumn.

And so it began to bloom. Some animals are ready to store food for hibernation, and some animals are looking for food and mates.
